Burt, St. Albans, N. Y., assignor to Mergenthaler Linotype Company, a corporation of New York Application January 8, 1942, Serial No. 425,983

26 Claims.

This invention relates to typographical composing machines, such as Linotype machines of the general organization'represented in Letters Patent of the United States No. 436,532 to O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned through distributing mechanism to the magazine from which they started.

More particularly, it relates to machines of the kind known to the trade as model 9, wherein a series of superposed magazines are mounted in a fixed supporting frame, and wherein the assembling mechanism includes a vertically adjustable throat .which may be brought into operative relation with any selected magazine by operating a hand lever located adjacent the keyboard. The magazines are slidably mounted in the supporting frame so that one or another may be removed therefrom when desired for interchange, and the assembling mechanism is hingedly mounted to permit it to be swung out of the way preparatory to the magazine removal operation. Heretofore, in effecting the interchange of a magazine, the services of a skilled mechanic have been demanded and the time ordinarily consumed has been objectionably long, particularly in modern composing rooms where the question of time s an important factor.

The present invention is intended primarily to improve these conditions and contemplates means whereby the uppermost magazine of the series may be quickly and easily removed for interchange by the operator of the machine and without the aid of a skilled mechanic. To that end, this particular magazine is supported in a subsidiary frame which overlies the magazine and which is upwardly movable to carry the magazine to a position where it may be removed without di turbing the assembling mechanism. To permit its removal, the magazine is slidably mounted in its supporting frame and held positioned therein by a latch bar which is easily accessible'when the magazine is in its raised position.

In the preferred embodiment illustrated, the supporting frame is hingedly mounted at its upper end in fixed brackets, and near its lower end and at its opposite sides it is provided with a pair of lifting cams which engage corresponding antithe machine frame.

friction rollers located directly beneath them in The lifting cams are attached to a horizontal rock shaft journalled in the magazine supporting frame and are adapted, by a partial turn in opposite directions, to raise and lower the magazine to and from a position above the assembling mechanism. Operation of the rock shaft is accomplished by means of a pair of arms pinned thereto and which ordinarily occupy an inconspicuous position out of the way alongside the magazine supporting frame. When it is desired to remove the magazine, these arms are swung forwardly into a position where they will serve not only to facilitate the removing operation but also to support the magazine at the front of the machine in the proper vertical position for handling.

As a means of safety, the present improvements also include a device for locking the rock shaft against operation while the assembler throat occupiesits uppermost position,this in order to prevent interference between the lower end of the magazine and the assembler throat as the former is lifted for removal. The construction of this device and the manner of its control will best be understood from the detailed description to follow.

Each magazine is providedwith a series of eS- capements to control the release of the matrices therefrom, and the several series of escapements are actuated by a single set of reeds mounted in a vertically sliding sash frame which carries the assembler throat and whichis movable upwardly and downwardly by operation of the hand lever before-mentioned, so as to locate the reeds'in engaging relation with the escapements of one magazine or another as desired. This single set of reeds is actuated by a set of main reeds which are in turn actuated through suitable connections from the keyboard in the usual way. In order to engage and disengage the single set of reeds with and from one or the other of the several series of escapements, they are mounted as usual in a secondary frame movable horizontally in the sash frame, the forward movement of which disengages the reeds from the escapements of the operative magazine preparatory to the shifting of the sash frame, and the rearward movement of which engages the reeds with the escapements of another magazine after the shifting of the sash frame, these respective forward and rearward movements of the secondary frame simultaneously disengaging the reeds from and engaging them with the keyboard connections.

To locate the sash'frame in its diiierentverti cal positions, the adjustable hand lever is provided with a latch dog which is arranged in engaging relation with a notched sector plate and which is actuated by a pivoted grip element associated with the hand lever and controlling the movements of a second lever for operating the escapement reed frame. In grasping the hand lever, the second lever will be actuated through the grip element first to retract the reed frame and then to disengage the dog from the sector plate so as to free the hand lever and permit it to be moved to any selected position determined by the notches in the sector plate. When the hand lever is released and the dog allowed to enga e the selected notch, both levers will be locked against movement and, through intervening rack and gear mechanism, the assembler throat as well as the escapement reeds will be located in operative relation with the corresponding magazine.

Ordinarily, the sector plate in the later Model machines s 0 arranged th the o h s th re n are o t of the l ne f vis o o the ov a or n ons era le ca and ski l must e exerci e in find n qu ckl h appropri te notch for a given adjustment. Here again the time element enters as a governing facto and, as an additional feature of the present invention, it is proposed to facilitate the operations above indicated. To this end, the vertical movements of the throat and sash frame are controlled from a crank shaft operable at will and which is adapted by a single revolution to effect the individual adjustments thereof. As it completes one revolution, the crank shaft is locked against accidental movement .by means of a spring-actuated latch member controlled by a hand lever which is arranged conveniently adjacent the crank shaft and also controls the forward and rearward movements of the escapement reed frame, the intermediate connections as herein shown comprising a bell crank lever and a. tubular shaft which is associated with the rack and gear mechanism for actuating said frame. The crank shaft, on the other hand, is connected through a vertical gear shaft and a short foreand-aft drive shaft to the usual horizontal shaft for actuating the rack bars of the sash frame. one arm of the bell crank lever is connected to the latch member and the other is arranged to engage one end of the tubular shaft, which latter is mounted on the horizontal shaft for a limited axial as well as a rotary movement. The latch member is arranged to engage a single notch formed in a collar fastened to the vertical gear shaft and, by such engagement, it is adapted to lock the crank against rotation through the connecting gears. When the hand lever is operated, the latch member will be withdrawn from engagement with the collar to release the crank shaft, and the tubular shaft at the same time will be actuated to move the escapement reeds forwardly to their inactive position preparatory to the rotation of the crank shaft and the vertical adjustment of the sash frame and throat. If only a minimum adjustment is required (i. e. from one magazine to the next) the pressure on the hand lever may be relieved as soon as the crank shaft starts its revolution, so that the latch member may be allowed to reengage the notch in the collar and the reeds allowed to resume their active position as the crank shaft completes its revolution. On the other hand, if a greater adjustment is to be made, it will then only be necessary to calculate the number of revolutions of the crank shaft required and. release the hand lever at the start of the last revolution. The crank shaft, of course, is provided with a handle which normally occupies a definite angular position so as to indicate to the operator when he has about completed a turn and therefore when to manipulate the hand lever.

In the accompanying drawings the invention has been shown merely in preferred form and by way of example, and it should therefore be understood that the invention is not limited to any specific form or embodiment except insofar as such limitations are specified in the appended claims.

The matrices X are stored according to font in four superposed magazines, the uppermost one of is designated A and the remaining three A Each magazine is provided with a series of escapements a, and any one of the four may be selected for use at will by the operation of a vertically adjustable sash frame B, which latter gives support to a throat B for conducting the matrices as they are released from the selected magazine into the vertical channels of a front plate C. The sash frame B is slidable in a rectangular frame member P and also carries a secondary frame D wherein is mounted a single set of reeds D adapted to actuate one series of escapements or another according to the adjusted position of the sash frame. The reeds D are operated from the keyboard (not shown) through a main set of reeds E and a corresponding set of pivoted levers E mounted in the machine frame (see Fig. 10). The vertical movements of the sash frame B are accomplished by the rotation of a horizontally disposed shaft B journalled in the frame P and provided at its opposite ends with a pair of pinions B meshing with a corresponding pair of vertical rack bars B secured to the sash frame at opposite sides thereof. As best shown in Fig. 9 the secondary frame D comprises generally the two upright side members D and a pairof toothed connecting cross bars D which latter project beyond the side members D into fore-and-aft grooves b formed in the sash frame, so that they may be moved rearwardly and forwardly to engage and disengage the reeds D with and from the levers E and the chosen series of escapements a. To insure true alignment of the throat B with a se-:

lected magazine and the reeds with the escapements, the upper extremities of the side members D of the secondary frame are formed with lips or hooks (1 adapted in the rearward position of said frame to engage corresponding notches a formed in the rigid side bars of the individual magazines. The forward movement of the secondary frame D is effected against the influence of four small compression spring d by a partial rotation of a short tubular shaft D mounted on the horizontal shaft B the shaft D being provided with a pinion D adapted to raise and lower a single rack bar'D which meshes with a pair of elongated pinions D associated, one with each of the toothed cross bars D As thus far described, the parts and their mode of operation are or may be the same as embodied in commercial machines of the type described or as shown in the patent to D. S. Kennedy No. 1,981,753 to which reference may be made if desired. It may also be noted that, as shown best in Fig. l, the assembling mechanism as a whole is hingedly mounted in a fixed bracket 0 at the right of the machine so that it may be swung out of the way for access to the magazines or when? ever it is desired to remove one of the lower magazines A Turning now to the principal feature of the present invention, that is, the manner of mounting the uppermost magazine A to permit its removal at the frontof the machine without disturbing the assembling mechanism, the magazine (Figs. 1, 6, 7 and 8) is supported by an overlying frame member F pivoted at its upper" end in brackets O rising from side members 0 of the main frame and provided near its lower end with a horizontal rock shaft)? which projects outwardly at both sides beyond the frame member to carry a pair of lifting cams F and also a pair of actuating arms F The supporting frame F, on its under side, is formed with a pair of fore-and-aft T-shaped grooves f, and" the magazine A on its top side is provided with tributing mechanism and the upper end of the magazine so that the distribution of matrices thereto may be carried on in the usual way.

The magazine A is positioned in the support ing frame F in a fore-and-aft direction by meansv of a centrally located latch member G (see Fig. 2) fastened to the rear end of a short rock shaft Cr and arranged to engage the forward cross rib A of the magazine. The shaft G is rotatably mounted in ears 0 and gr depending from a plate Gr secured to the supporting frame and is provided at its front end with a handle G which is movable in opposite directions to engage and disengage the latch member G with and from the magazine. A stop pin 9 projecting inwardly from the handle above the plate G limits the movements of the handle and stops the latch member G in its active or inactive position. The plate G is mounted on the frame F by means of clamping screw and slot connections g so that it may be adjusted longitudinally when desired to regulate the position of the magazine relatively to its supporting frame and the assembling mechanism. The adjustment of the plate is effected by a set screw 9 mounted alongside the shaft G in the front depending ear 9 of the plate and anchored in the frame F against endwise movement by a pin 9 which engages an annular groove formed in the shank of the set screw. When an adjustment is required, it is merely necessary to loosen the clamping screws g turn the set screw 9 one way or the other to shift the plate G2 and latch member G to the proper position, and then retighten the clamping screws.

With the parts in the full line position shown in Fig. 1, the magazine A is sustained in its operative position through the engagement of the lifting cams F with a pair of anti-friction rollers O mounted in vertical bracket plates 0 rising from the side members 0 of the main frame. When it is desired to remove the magazine, the actuating arms F are swung forwardly to the position indicated by the broken lines in Fig. 1, so as to rotate the rock shaft F and through the lifting cams F raise the supporting frame F and the magazine above the assembling mechanism, the movement of the parts involved in this operation being limited bythe engagement of the rollers O in corresponding recesses) formed in the outer edges of the cams F (see Fig. 6). The short rock shaft G may then he turned by means of the handle G to disengage the latch member G from the cross rib A of the magazine and the latter thus allowed to slide forwardly out of the frame F onto the arms F which now serve not only to facilitate the removing operation but also to support the magazine thereafter in a convenient vertical position for handling. In

this connection, it may be mentioned that the arms F are capable of giving the desired verticalisupport to the magazine through the engagement with the customary hooks at their extre'mities with the upper magazine reinforcing rib A which for the purpose is extended (see Fig. 7) beyond the opposite sides of the magazine A. After a new magazine has been pushed into the supporting frame F and locked therein by the latch member G, the arms F are swung backwardly to lower the magazine into operative position under control of the cams F A cover plate F fastened to the supporting frame F, serves to conceal from view certain moving parts carried thereby and thus to improve the general appearance of the whole structure.

As a safety feature, to prevent accidental release of matrices from the magazine A during its removal and replacement, it is proposed to lock the escapements a thereof against actua-V;

tion as the magazine is raised preparatory to its removal and to unlock them for normal operation as'the magazine thereafter is returned to its original or operative position. Accordingly, the magazine is provided with a halfround rock shaft a (Fig. 10) mounted in the escapement frame and extending completely across the magazine in engaging relation with the escapements. The rock shaft 11 is operable by means of a crank element a secured to one end thereof, and is adapted by a quarter turn in opposite directions to lock and release the escapements a. The crank element a is provided with a pull spring a which tends to turn the shaft in the appropriate direction to engage the escapements, and an angular bracket plate (2 which extends inwardly from the contiguous frame member into the path of the crank element a is adapted through its engagement therewith to turn the shaft against the tension of the spring a in the other direc tion to release the escapements. In other words, when the magazine is lowered into operative position, the rock shaft will be turned to its inactive position by the engagement of the crank element with the bracket plate; Whereas, when the magazine is raised preparatory to its removal and as the said element is carried out of its engagement with the bracket plate a the spring a will be permitted to turn the shaft into locking engagement with the escapements. A stop pin a which projects outwardly from the escapement frame in engaging relation with the crank element a serves at the time to limit the rotation of the rock shaft.

As another safety feature, to prevent lifting of the magazine A for removal while the sash frame 3 and the assembler throat B are located in operative relation therewith, the rock shaft F for the reasons already stated and as shown in Fig. l, is locked at this time against operation by means of a horizontally disposed lever H, the longer arm H of which is formed with a hook-shapedend portion h arranged to engage a stud f projecting outwardly from an arm F depending from the shaft F The lever H is pivoted to the side frame member 0 and is operable from the sash frame B through a second lever E (Fig. 9) pivoted to the frame of the assembling mechanism and arranged to en-' gage'the shorter arm H of the lever 1-1. When the sash frame B is lowered out of its operative relation with the magazine A, the lever H is allowed to disengage the lever I-I, so that the hook h of this lever may drop by gravity out of its engagement with the stud f and, conversely, when the sash frame is again shifted to its uppermost position, it actuates the lever 1-1 and through it rocks the lever I-I so as to reengage the hook with the stud f Stop pins h and 71. sustain the levers H and H respectively, in their inactive position.

In the present instance and as before stated, the aforementioned short tubular shaft D is mounted on the shaft B for axial as well as rotary movement, and its operation is controlled from a hand lever J depending from a rock shaft J to which it is pinned (Fig. 5). Adjacent the hand lever, the rock shaft J is provided with a bell crank lever J one arm of which i forked to straddle the shaft B and engage a flanged collar 1) formed at one end of the tubular shaft D and the other arm of which is connected by means of a vertical link J to a pivoted latch bar K, the purpose of which will presently appear. The

tubular shaft D (see Fig. 14) is connected to the shaft B by means. of a pin d and a short spiral slot 01 formed in the collar D so that, by moving the shaft D endwise, it will be turned at the same time to actuate the vertical rack bar D through th pinion D which latter is keyed by means of a tapered pin d to the other end of the shaft D The pin (1 passes through a slot 1) formed in the shaftB and made sufficiently long and wide to permit, not only the endwise movement of the tubular shaft, but also the partial turning thereof necessary to operate the rack bar D A pull spring d anchored to the pin (1 and connected to the flange of the collar D holds the tubular shaft yieldingly in its normal angular position in the shaft B and as determined by the pin d It will now be seen that, by moving the hand lever J from its normal position, as shown by the full lines in Fig. 9, to that indicated by the broken lines in said figure, the shaft D will be pushed by the forked arm of the lever J a limited distance along the shaft B and simultaneously turned against the influence of the spring (1 in the appropriate direction to raise the rack bar D and, through the intervening connection before described, move the escapement reed frame D forwardly to its inactive position. As the hand lever is released, the springs 01 and the spring d act concurrently to lower the rack bar D and restore the frame D and shaft D to their original positions.

As another feature of the present invention, the operation of the shaft B in adjusting the sash frame D from on magazine to another, is controlled from a short fore-and-aft shaft L mounted in a bracket P secured to the rectangular frame member P of the assembling mechanism, said shaft being adapted by a single revolution in one direction or the other to effect the individual adjustments of the sash frame. As best shown in Fig. 4, the shaft L is provided with a crank handle L and operatively connected through a pair of bevel gears L to the lower end of a vertical shaft L also mounted in the bracket P and which is similarly connected at its upper end by means of another pair of bevel gears L to a short drive shaft L The shaft L is provided about midway of its length with a collar L formed with a single notch Z which is arranged in engaging relation with the beforementioned latch bar K whereby the crank shaft may be locked against rotation. Motion from the drive shaft L is imparted to the horizontal shaft B through the medium of a worm wheel L and a gear L integrally connected together and rotatably mounted on a stub shaft L the worm wheel L engaging with a worm L keyed to the drive shaft, and the gear L meshing with a pinion B secured to one end of the shaft B The hand lever J, as may be observed (Fig. ,4), is arranged conveniently adjacent the crank handle L and, due to the leverage obtained as well as the ratio of the gearing and the Worm drive, an adjustment of the sash frame B may be quickly and easily accomplished even though both hands are required to perform the operation, it simply being necessary, first to swing the hand lever J a limited distance in the appropriate direction to move the escapement reed frame D to its inactiveposition in the manner above described, and then to turn the crank handle L through one, two or three revolutions to effect any desired adjustment of the sash frame. By the first operation, the latch bar K .will be automatically disengaged from the collar L and, as soon as the second operation is started,

has been turned through one complete revolution, at which time the notch l in the collar L will again register with the latch bar K (compare Figs. 4 and 5). Now, as the bar K snaps into the notch l, the shafts L and L willbe locked against rotation and the sash frame located in its newly adjusted position. Undue strain on the locating pin d for the tubular shaft D by operation of the hand lever J is countermanded by means of -a banking screw 7' (Fig. 9 projecting laterally from said lever and arranged to engage a portion of the bracket P Also, the crank shaft L, the vertical shaft L and the drive shaft L are all provided with thrust bearings L to facilitate their movements and reduce the physical efiort required to operate the crank handle L It is believed that the variou parts, their construction and mode of operation have been sufficiently described and that any further description would be superfluous.
